| Folks often ask whether hummingbirds are nocturnal; i.e., whether they forage at night. As indicated by this March 2003 photo (above) from Michael Alexander, Anna's Hummingbirds at least feed after sunset. Michael reports that during the day one bird will drive others away, but at dusk they feed together without altercation at this Coulterville, California locale. (The black background is an artifact of the camera flash; Michael says the sky was not completly dark when he took the photo.) All the hummers above appear to be adult males; females are likely on their nests incubating or brooding, lest the eggs or chicks succumb to the cool of the evening.
For a splendid illustration of what an adult male Anna's Hummingbird looks like by day, see the November 2002 photo below taken by Sam Sumida of Avinet. Note the metallic color off the male's gorget extends to the entire head and also forms "sideburns." |
